organizers say they are here to send a message to congress to tell them to shut down immigrant detention across the country. one of the most emotional speeches was given here. you're here with your 5-year-old daughter roxanna. you cried before the crowd today. why did you feel compelled to speak? she said she wants her family to be reunited, hallie. her husband was deported. and he was held in this facility. you've also told me you're giving voice to some of the mothers you have seen crossing the border lately. of course, she says, i have children. and i can't imagine a child being put in a place like that.
